β-Angelica lactone, a model of chiral butenolides, has been efficiently reacted with electron-rich dienes under high pressure conditions, with an excellent diastereofacial, regio- and endo-selectivity, giving the expected adducts in good yields. Some derivatives have been prepared.
β-当归内酯,一种手性丁烯内酯的模型,已在高压条件下与富电子二烯有效反应,具有出色的非对映面,区域和内选择性,可提供预期的加合物,并具有良好的收率。已经制备了一些衍生物。
